He said: "You can't claim to be in the common ground of British politics when you’re cutting the tax credits working families rely on, leaving 3 million of them on average £1,300 a year worse off.

"You can’t claim to care about the housing crisis when you’ve overseen the lowest level of housebuilding in peacetime since the 1920s.

"And you can’t claim you care about the NHS when you’ve pushed up waiting lists, made it harder to see a GP and plunged hospitals in to financial crisis."

During the speech the PM announced:

The government will order four new Trident submarines despite Jeremy Corbyn's opposition - with no mention of a Commons vote

The Tories have reached a deal with housing associations to let in the Right to Buy next year . But the National Housing Federation implied he had backed down, claiming the proposal was their own compromise which 'addresses our initial concerns around supply and independence'.

Tories will make every school an academy and make councils running schools a thing of the past

The speech included a damning attack on the left, saying: "it's not just that their arguments are wrong. It's the self-righteous way they make them. These deficit deniers running around saying we're hurting the poor."

To Labour he said: "You're not for working people but for hurting people. If you want a lecture about poverty ask Labour. If you want something done about it come to us, the Conservatives."

The PM moved onto an attack on Jeremy Corbyn which quoted his comments on Osama Bin Laden out of context.

"A tragedy is nearly 3,000 people murdered one morning in New York. A tragedy is the mums and dads who never came home from work that day. A tragedy is people jumping from the towers after the planes hit.

"My friends – we cannot let that man inflict his security-threatening, terrorist-sympathising, Britain-hating ideology on the country we love."

Unite general secretary Len McCluskey added: "This fools nobody. We need to build at least 240,000 additional homes annually to keep up with the new households that are formed – last year only 140,000 were built."

Mr Cameron addressed swirling leadership pitches with high praise for 'iron chancellor' George Osborne and 'our very own Boris Johnson'.

On prisons he said 'we've got to get out of the sterile, lock 'em up and get 'em out debate' beloved of his Tory predecessors.

He added: "When our prisons are relics from the time of Dickens it's time to sell them off and build new ones that actually work.

"This is going to be a big area of social reform in the next five years and I've got just the man for the job.... the great conservative reformer, Michael Gove."

For the first time in nearly 20 years the Prime Minister walked on stage in command of an all-Tory government - and celebrated with a triumphant video documenting his election win soundtracked by Coldplay.

There were laughs from the 2,000-strong audience as images flashed up of the infamous 'EdStone' and a rousing cheer when footage was played of the exit poll that stunned the country on May 7.

Tory chiefs humiliated Labour big beast Ed Balls by showing footage of his shock defeat in Morley and Outwood, prompting cheers of 'wheey!' from the delegates.

And as the PM took to the stage he declared: "When you put your cross in the Conservative box you are putting your faith in us to finsh the job we started.

"It only takes two words to cheer me up - exit poll"

He added: "As dawn rose a new light, a bluer light, fell across our isles."

He told delegates he was surrounded by 'half packed boxes and bin bags' in his Number 10 flat preparing for defeat.

"I was preparing to go and see her Majesty and thought 'I'll just go and lie down and let it all sink in'", he said.

When he woke up Nigel Farage and Ed Balls had both lost - and 'there was a moment where I thought I'd died and gone to heaven'.

Asked why the pollsters were so wrong, he said: "Let me put it as simply as I can. Britain and Twitter are not the same thing."
